模拟试验

The results of simulating multi-stage H〓O〓 displacement bleaching showed that the brightness of bleached pulp increased along with the increase of H〓O〓 concentration in fresh bleach liquor.

多段H〓O〓置换漂白的模拟试验结果表明，漂后浆白度随新鲜漂液H〓O〓浓度的提高而提高，但在相同的新鲜漂液H〓O〓浓度下，不同漂液量时的漂后浆白度基本相同。H〓O〓消耗量随新鲜漂液H〓O〓浓度和漂液量的下降而下降，漂白效率的变化恰与H〓O〓消耗量的变化相反。
